This example displays a tree diagram of the Netflix ecosystem, breaking down content into originals and licensed shows, and technology into engineering and product management branches. The visualization uses interactive nodes that expand and collapse on click, with each node and its label colored to match the data. Built with D3.js v7 and rendered as SVG, the code employs `d3.tree()`, `d3.hierarchy()`, and `d3.linkHorizontal()` to compute the layout and draw curved links. Node sizes and positions animate smoothly via the update function, while colors come from the embedded `treeData` array.
